Our invention relates to double poppet angle check valves.

It is the obj ect of our invention to provide a self-sealing double poppet angle check valve adaptable to be mounted in a fluid supply system, particularly one handling volatile liquids and so located in the system that 1 ground, it is easily accessible, and byso arit will be above ground where it is easily accessible, thereby eliminating the present prO blem of getting access to various types of foot valves which are diiiicult to adjust or repair or replace because they are buried in the ground. Y

Referring to the drawings Figure 1 is a diagrammatic layout of a 'fluid supply system embodying the valve showing its general location;

'Figure 2 is a-vertical section` through the valve showing the poppets in full lines;

Figure 3 is a top plan view of the poppet valve;

Figure 4 is a section on the line 1 -4 of Figure 2 with the poppet valves removed.

Referring to the drawings in detail, 1 is a tank connected by the pipe 2 to the valve casing 3 to which is connected an outletJ pipe 4. The inlet side of the casing 3 is threaded at 5 to receive the pipe 2. Spaced above this threaded portion 5 is an inwardly-extending shoulder 6 threaded at 7 to receive and support a valve cage 8 which is provided with an inwardly extending, upwardly projecting sharp' edged valve seat 9 adjacent the pas# sageway 10 in which is also located a spider 11 having an apertured sleeve 12in the center thereof for guiding the poppet valve stem 13. The valve proper 14 rests upon the edged valve seat 9. A center stud 15 on the upper side of the valve is adapted to engage with the lower end of the valve stem 16 of the second poppet valve 17.

An extension of the cage 8 upwardly into a sharp edged rim 18 around the aperture 19 forms the support for the upper poppet valve 17. The poppet valve 17 has an upwardly extending stem 20 loosely fitting within the guide sleeve 21 of a detachable cap 22. This cap is threaded into the casing at23 by an aperture which is suiiiciently large to permit of the insertion of the valve cage 8 and the A21 to escape.I

cage S is large enough to permit ot' the insertion of the smallerpoppet valve 14. A relief port .24 is provided in the sleeve 21 to allow the air compressed by the stem 20 in the sleeve As this poppet valve is located above ranging the parts that they may be placed Yin position through a common aperture which is replace and repair the severalA elements ofthe combination without digging uptheground or dlsturblngthe rest of the mechanism to which the valve is attached.

It` will beunderstood that we desireto'conrprehend within our invention such modilications as may be necessary to'adapt it to varying conditions and uses. n Y

Having thus fully described our invention,

what we claim as new and desire to secure'lby Letters Patent, is

1. In combination, a valve casing hav .'60 closed by the cap22 it is possible to adjust,

ment of one will move the other while they may move a predetermined distance inde- 'y pendently one of the other.

2. In combination, a valve inlet and exit ports, aV valve therein on a shoulder thereof, said cage having spaced valve seats projected inwardly ot casing having cage threaded said cage, a spider adjacent one ot-said'scats for guiding a valve, a valve having a depending guiding stem and upwardly projecting valve lift stem, a second superimposed poppet valve having a depending valve engaging stem and an upwardly extending valve guiding stem, and means to guide said last mentioned stem. l Y

3. In combination, a valve casing having inletand exit ports, a Vvalve cage threaded therein on a shoulder thereof, said cage having spaced valve seats projected inwardly, a spider Onsaid cage adjacent one of said seats 2 j' Y Y 1,808,074

for guiding a valve, a vvalve having a depending guiding stem and upwardly projecting valve lift stem, a second superimposed poppet valve having a depending valve en-.- 5 gaging stem and an upwardly extending valve l guiding stem, and means to guide said lastV mentioned stem, said guiding means beingvformed in a detachable closureY member" mounted in said casing. A t ll. In combination, Va valve casing having inlet ,and exit ports, a valve cage threaded Y therein on a shoulder thereof, said cage hav- 4 ing spaced valve seats projected inwardly, a spider on said cage adjacent one of said seats for guiding a valve, a valve having a depending guiding stem and upwardly projecting Vvalve lift stem, a second superimposed poppet valve having a depending valve engaging stem and an upwardly extendingfvalve guiding stem, and means to guide said last mentioned stem, said guiding 'means' being formed in a detachable Closure member mounted in said casing of suiicient size for the removal therethrough of said Cage and said valves. j

5. In a valve structure, a casing having` an inlet and an outlet'and an openingga closure 'for Asra-id opening, a sleeve on said closure projecting into the casing, a valve cageadapted i tobe inserted through 'said opening andremovably supported Aby said casing, and. a valve member forsaid cagehaving a stem projecting into said sleeve and guided `thereby, said sleeve having a relief opening for the passage of fluid to and from the sleeve behind the stem.

6. In a valve structure, avalveV casing having an opening therein, a closure for said opening, an inwardly Vprojecting sleeve on 4 0 said closure with a passageway therein, and a valvemember in said casing havinga stem projecting into and guided by the sleeve, said passageway serving as aa'elief opening for the iiow of fluid to and fromY the sleeve behind the stem. y Y j,

In testimony'whereof, we axour signatures.
